The APS Unit is an Arduino based security system built by Bruce Johnson. There are several tutorials, on the Arduino4U website, that show you how to build this security system yourself. If you like what you see, please leave a comment on this blog, thanks! :)
My name is Bruce, I first started using Arduino with Little Bits the Christmas of 2014. I then decided to purchase an Arduino Uno board. Finally in March of 2015 I decided to buy an Arduino Mega board!That lead to the idea of the APS.
